Isn't Italy a little geologically unstable? I'd be a bit nervous, going through a long tunnel, in a region known for vulcanism and earthquakes.

I'd be a bit nervous, going through a long tunnel, in a region known for vulcanism and earthquakes.
- AnimalMuppet 11mo agoIt is unstable, but (I think) more so in the south. I'm not sure that the Alps region is unstable.
- whizzter 11mo agoItaly isn't a puny country, it's over 1000kms between Sicily and the Alps (Like LA to Albuquerque), seems the fault lines reaches northern Italy (about 100km from the alps) but the amount of larger quakes seems smaller there.
- eCa 11mo agoThe 57 km Gotthard Base Tunnel has been in operation since 2016. There's also a 3km long tunnel between France and Italy that opened in 1882. Nowadays there's probably hundreds of 1km+ tunnels in the Alps.
- ChrisMarshallNY 11mo agoWell, from the other responses, it seems the Italian Alps are pretty stable.
- tacone 11mo agoYes but we're drilling holes through them to fix that.
- gunzel412 11mo agoLet me introduce you to the Seikan Tunnel [1] between the islands of Honshu and Hokkaido in Japan, 53.85km with 23.3km of that under the sea. [1] https://en.wikipedia.org/wiki/Seikan_Tunnel https://en.wikipedia.org/wiki/Seikan_Tunnel
- ChrisMarshallNY 11mo agoNow, that’s scary. I do know that the Japanese have the world’s best anti-earthquake architecture (because they need it), but it’s still scary.
- bobthepanda 11mo agoTunnels are actually pretty safe in earthquakes, Japan for example is criss crossed with them. A tunnel is actually the least likely to shake; if you shake a jello with fruit inside it, the surface moves a lot but the interior fruit won’t move all that much.
